Hello Lovingit,
I think u need study docs provided
www.CIC.gc.ca. You donot need to pay $10000 when you get there. It may take one, two, three or more years depending on location where u apply. If you live in USA, then Buffalo is best option for you to apply. It takes less than two years. For details of other please visit processing times on ww.cic.gc.ca.
Every one who is interested in immigration, has to go through a medical process. For that CIC will inform you where to have your medical checkup. There are CIC authorized Doctors all over the world who carry out medical checkup on behalf of cic and then send our reports to cic. Offcourse we have to pay Dr's fees.
Thanks
Cool
